Lane closures on Route 59, a water-main dig on Ogden Avenue, rotating full closures on Book Road — Naperville has a lot of orange barrels right now. This page tracks the major road projects in and around the city, drawn only from official City of Naperville, IDOT, Illinois Tollway, and DuPage County sources.
How to use this page: every project below names its official source, and timelines are stated exactly as the agency publishes them — construction schedules shift with weather and field conditions, so check the source link before a trip that matters.

IDOT is resurfacing Illinois 59 on the Naperville–Aurora line, with pavement patching and new ADA sidewalk ramps. It's a $4.6 million Rebuild Illinois project, and the road stays open throughout.
The city is replacing the cast-iron water main installed in the 1950s and 1960s with a new 16-inch main, along with the water valves, hydrants and services along the route. Crews generally work Monday–Friday, 7 a.m. to 3:30 p.m., and are usually off site by 5 p.m.
The DuPage Water Commission is building a 30-mile water main extension to bring Lake Michigan water to Montgomery, Oswego and Yorkville — six of those miles run through Naperville. Phase one installs a 54-inch main beneath Book Road, and residents are asked to follow the posted detour routes.
The corridor is being widened to two lanes in each direction plus a center turn lane, trail and sidewalk, and the roughly 110-year-old Canadian National/Wisconsin Central railroad bridge is being replaced. The earlier full closure between Pennsbury Lane and Frontenac Road has been lifted and the road is open to all traffic; drainage, storm sewer and utility relocation work (including a new Nicor gas main and ComEd line moves) continues through the fall, and the city advises more closures will be needed next year.
The Illinois Tollway is upgrading the toll plaza at the Freedom Drive/Naperville Road interchange on the Reagan Memorial Tollway (I-88), part of its systemwide toll plaza improvement program. Traffic on the ramp is currently reduced to a single lane, and the Tollway schedules periodic ramp closures — most recently an overnight full closure of the ramp to westbound I-88 for tolling equipment installation (midnight Sat, Oct. 3 to 5 a.m. Sun, Oct. 4), with no detour posted.
Just east of Naperville, IDOT is resurfacing Illinois 53 (Rohlwing Road) from south of 75th Street to the Will County line through the Lisle area — a route many east-side Naperville drivers use daily.
The city's Water and Wastewater Utility is finishing water main replacements on residential streets in three neighborhoods: Saybrook (Phase III — including Barley Ave, Case St, Loomis St and N. Wright St, now in the landscaping-repair stage), Maplebrook (Phase 2 — including Olympus Dr, Tamarack Ave and Sandpiper Ln) and Kings Terrace (including Charles Ave, Catherine Ave and Richard Rd). Crews generally work Monday–Friday, 7 a.m. to 3:30 p.m.
DuPage County's 2026 Transportation Capital Program includes a Naperville Road intersection and channelization project in Naperville, including traffic signal replacements at the intersections with Diehl Road and Naperville-Wheaton Road. The county's announcement does not publish construction dates — we'll move this to "active" when the county posts a schedule.
The second phase of the Ogden Avenue water main work would extend the new 16-inch main west from Washington Street to approximately 1,000 feet beyond Mill Street, toward Naper North High School. The city has postponed this phase until 2027 due to IDOT permitting and other factors.

No — IDOT lists the impact of the Route 59 resurfacing between McCoy Drive and Artesian Road as daytime lane closures, not a full closure. Expect delays during the day while the resurfacing, patching and ADA ramp work runs through fall 2026.
Sections of it are. The DuPage Water Commission's WaterLink pipeline closes Book Road fully, one section at a time, between just north of 75th Street and 103rd Street — the whole stretch is never closed at once, and the city asks drivers to follow the posted detour routes. Work along Book Road is expected to continue into the spring of 2027.
The city's October 8, 2026 update says the Ogden and Washington water main replacement is scheduled for completion by the end of November, with ongoing lane closures and traffic pattern changes until then. Crews generally work Monday through Friday, 7 a.m. to 3:30 p.m.
